To all whom, it may concern:

Be it known thatI, DANIEL J. FILKINS, of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Engines, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming a part hereof.

My invention relatesto engines; and it consists of the novel construction, combination,

and arrangement of parts hereinafter shown,

described, and claimed. 4

The principal feature of this engine is the valve of peculiar construction, as shown, said valve being held in a rigid position within the steam-chest and is provided with a horizontal partition, and the upper half of the main plate of the valve is housed in, and the ports in the upper half of this housed-in portion are exhaust-ports, the ports in the lower half being the steam-inlet ports. end of the cylinder is weighted in order to equalize the weight of the piston-rod. 1 (1on sequently the entire cylinder oscillates in its bearings very easily and with practically no vibration and is always balanced on the first and last quarter of each stroke of theengine and at thesame' time furnishing extra weight, at point of wrist-pin on crank-shaft while the piston is passing each center.

Fig.8 is avertical sectional view of the front head of the cylinder, showin g the bearing andoil-receptaole for the piston-stem. Fig. 9is a side view of the valve, drawn to a small scale, showing the manner in which the valve face-plate is appliedthereto.

1 isa base having formed integral therewith bearing-uprights 2, each supporting a journal-bearing, an oscillating cylinder 3,

The right-hand having at-its one side an integral projecting bearing 4, which is supported in a journalbox 5, formed on the top of one of said uprights 2. Opposite to said bearing 4 on'said cylinder 3is formed integral a steam-chest 6, divided from the cylinder by a partition 7, forming a partvof the cylinder and having in its center a' bore 8, in which is to engage a pin 9, formed on the stationaryvalve 10. The steam-chest is provided with a head 11, secured thereto by bolts or studs 12 and held steam tightby means of packing material 13, placed between the head and contact edge of said chest. The head is provided with a rightangular circular projection 14 of sufficient size to fit snugly over a combined valve supply and exhaust pipe 15 and held air and steam tight by packing material 16, (see Fig. 4,) placed between said projection and shoulder of said valve. This projection 14 is mounted and adapted to oscillate in a journal-bearing 17, mounted upon one of said uprights 2. y u

To the end 18 ofthe cylinderlprovidea coneshaped head 19,- constructed'of solid'material, and it is held thereto by bolts in the usual manner and designed to provide extra weight at said end when the piston-head is past the center in said end of the cylinder to aid in os cillatingthe same at an upward angle, assisting the piston to pass its center on the crankshaft. To the end 20 of said cylinde I provide a head 21, which is also, cone-shaped in form, but constructed as shown in the sectional-view, Fig. 8, consisting of a hollow shell 22, separatedfrom the cylinder-space by a wall 23, in whichis formedan opening 24. for theadinission ofthe piston-stem 25. -Within :the shell and secured to the partition 23 is a stuffing-box 26 for carrying packingfmaterial, and communicating therewithis a gland 27,

extending horizontally from said stuffing-box to the end'of said shell and having aprojecting flange 28, in which is to come in contact a screw-cap 29, also forming a stuftingbox, andis applied to the end of said shell. The gland 27 has aportion of itself hollowed to a larger diameter than the piston-stem 25 and is provided with a plurality-of apertures 32,

through which oil is adapted to pass from the shell 22,acting as an oil-receptacle, down into communication with the piston-stem 25 for lubricating the same. The object of this gland is for the purpose of making a steam and oil tight bearin g upon said piston-stem, and it is tightened by means of the cap 29, coming in contact with the flange 2S, pressing it inwardly against the packing material placed in the stufling-box 26, and also act-s as a guide and support for the piston-stem. The pistonstem serves as a connecting-rod and is connected direct.to the crank-shaft 33, forming part of the driving-shaft 34, held in journal'- bearings formed 011 the uprights and operating drive and balance wheels 35.

Referring to Figs. 4 and 5, the stationary valve 10 has a face-plate 10, provided with a tenon 10", extending across its entire width, and is for the purpose of allowing the steam in the steam-chest to press against said plate, making a tight joint between said plate and partition 7. The tenon 10 will allow said plate to act, yet prevent same from turning. The plate 10 has provided in its face two steam ports 36 and 37 and two exhaust-ports 3S and 39, the exhaust ports being formed through the tenon 10. In this manner the steam cannot gain access into the exhaustports between the plate 1O and valve 10. The

steam-ports communicate with the space 40 of the steam-chest, which is supplied with steam through an opening 41, formed in the bottom of the pipe 15, communicating with the steam-supply passage 41, located at the bottom, and the exhaust-ports open intoa Y- shaped duct 41", formed in said valve and terminates in the pipe 15, having its exhaustpassage 42 at the top. Said passages of the pipe 15 are separated from each other by a horizontal division-wall 42.

The end of the pipe 15 communicates with a T-coupling 43, having cars 43, (see Figs. 4 and 5,) which is held by means of bolts 44, passing through said ears and through a flange 45, formed on a collar 45, passing around the pipe 15 and a portion of the T- coupling 43, and is provided with a flange 46, having apertures 47, by which said flange is secured to the standard 2 by means of bolts 47. (See Fig. 2.) The T 43 has passages arranged to communicate and be in alinement with the passages 41 and 42, and to the bottom of said T is connected the steam-supply pipe 48, passing downwardly and conneeted to an elbow 49, connecting said pipe with the pipe 50, having at its end a T 51, carrying a blow-off or air cook 52. To the .top of the T 51, by means of a stuffing-box,

is held a pipe 53, carrying a governor-valve 54, which supports the governor and its mechanism 55. To this valve 54 is connected a pipe 56, which leads to the boiler. The governor mechanism is operated by means of a belt 57, passing over a pulley 58, located upon the driving-shaft 34, and over a pulley 50, mounted upon the shaft of the governor mechanism.

The journal-bearing 5 is provided with an adj ustingmechanism 60, which comes in commu nication with the integral projection 4 and is for the purpose of adjusting the cylinder and steam-chest in close communication with the stationary valve 10, bringing their contact-faces in a steam-tight connection.

The operation of my improved engine is as follows: \Vhen it is desired to start the engine, the steam-valve is operated, which will allow the steam to pass through the pipe 56,

through the governor-valve, downwardly through the pipe 53, T 51, and thence through the pipe 50, and upwardly through the pipe 48 into the T-coupling 43, through its bottom port, which is in alinement and communicates with the passage 41 of the pipe 15, passing, as indicated by the arrow in Fig. 4, down through the opening4l into the space 40 of the steam-chest, through the port 36 into the port 65, formed in the partition 7 of the cylinder, and through the port-opening 64 into the cylinder against the piston-head 63, driving the same to the opposite end of said cylinder. The steam which is in the cylinder in said opposite end is then forced by the pistonhead through the port-opening 62 in the opposite end of the cylinder, through the port 61 in the partition 7, and will pass through the port 39 into the Y-shaped duct 41, as indicated by the arrow, through the passage 42 into the exhaust-pipe, which is to be located 011 the top of the T-coupling 43. After the piston-head has reached the opposite side the steam passes from the space 40, supplied by the passage 41, by means ofthe opening 41, through the port 37 into the port 61, and through the port-opening 62, pressing against said piston-head, bringing it into the position opposite that shown in Fig. 4, and the exhaust is then driven through the port-opening 64, through the port 65, through the opening 38 into the Y-shaped duct 41", into the exhaust-passage 42, and out. The ports of the partition 7 of the cylinder alternately come in communication with the valve-ports 36 and 37 and exhaust-ports 38 and 39 by means of its oscillating action, which can be seen in Fig. 3.

The engine may be reversed by reversing the valve mechanism, which will place the supply-pipe on the top and the exhaust at the bottom. This can readily be accomplished by loosening the bolts 47, which will then allow the operator to reverse the entire valve and T-coupling 43 and entire cylinder by reversing the heads, and when the opposite openings of the flange 47 come in c0mmunication with the opposite openings in the journal-box the bolts are then secured therein, and in this manner the engine is reversed.
